President Obama jokes about Sen. Marco Rubio at White House Correspondents Dinner

In speaking about Sen. Marco Rubio and the 2016 presidential race, President Obama quipped: "The guy has not finished a single term in the Senate and he thinks he's ready to be president. Kids these days!"

Later, the state of Florida was the subject of a joke by Conan O'Brien, who compared the Sunshine State to North Korea.

"Kim Jong-un doesn’t understand we already have an unstable peninsula that will take down America – Florida," cracked O'Brien.
